I am thinking about buying a 98 Astro 2050.It has a 98 Mercury 225 on it.Very nice boat.But its a repo.The dealer said i can try it out before buying.He also said he can sell me an extended warranty for 2 years at 1500 bucks.He didnt push that topic ,i did.I know very little about outboards.What should i do? BTW does 16,250 sound high for this boat,it looks very excellent and very clean.
